Welded flange basic information analysis? Welded flange depends mainly refers to the mechanical properties of the carbon content of steel, but generally do not add a lot of steel alloying elements, sometimes referred to as carbon steel or carbon steel. In the industrial pipeline, using welded flange connection is very extensive. Within the family, the pipe diameter is small, but low pressure, invisible welded flange connection. If a boiler room or production site, everywhere flanged pipes and equipment. Welded flange distortion, sealed, and widely applicable to large fluctuations in pressure or temperature pipelines or temperature, high pressure and low temperature of the pipe, the advantage of cheaper prices, nominal pressure of not more than 2.5MPa; also used to transport price expensive pipeline flammable, explosive media, nominal in PN16MPa around. Alloy steel tee, flanges, reducers, such as high voltage fittings with today's domestic first-class production equipment and testing equipment and a variety of pipe fittings elbow flange assembly line where the cold forming sliding forging hot forging machining and other heat various process is complete the company also has a variety of testing equipment, such as non-destructive testing chemical analysis metallographic examination physics experiments and other technical force capable of producing American standard Japanese standard GB standard specifications of the stainless steel flanges, tees, reducers and other products Ministry of Chemical Industry has been selected for the National Power Corporation designated collaboration manufacturers. ? Welded flange using the actual production and the development of different production methods and processes and production methods and processes in accordance with the principle of the different aspects of an important value and role, adding a certain element in the actual production adding features and value of carbon steel flanges, showing good use of the characteristics and value. Flanged easy to use, able to withstand greater pressure. ? Depending on the level of pressure welded flange pad there are different materials, from low pressure asbestos pads, high pressure asbestos pads to the metal pads are.
